CLEAN WATER AND SANITATION
Ensure access to water and sanitation for all
Over 2,000 million people in the world live without access to a basic drinking water service, and 3,6 billionhave no access to a basic sanitation service, resulting in avoidable deaths, chronic disease, fewer hours of education and low productivity.
ACCIONA has positioned itself as a key player in the water treatment sector. Its innovative management seeks to resolve the challenges with respect to the shortage of water resources.
CLIMATE ACTION
Take urgent action to combat climate change and its impacts
The generation and use of energy accounts for 35 % of total greenhouse gas emissions in the world. This activity is the largest contributor to global warming. Investment in renewable energy, energy efficiency and other low-carbon technologies will continue to be essential to meet the emerging needs of humanity and to minimize their negative impact on the environment.
ACCIONA considers the fight against climate change and its effects to be a strategic priority. The company works to mitigate greenhouse gas emissions in order to contribute to the progress of society and respond to the main challenges of sustainable development in the areas of infrastructure, water and energy, leading the transition to a low-carbon economy.
Currently, nitrogen (N) removal in wastewater treatment plants (WWTP) accounts for 20% of their energy consumption. The NIMBI process will help to reduce this energy consumption and the associated carbon footprint, mainly related to the aeration used for the oxidation of organic matter and the nitrogen load. Furthermore, the cell will allow the methane enrichment of the biogas stream obtained from anaerobic digestion. Finally, an ammonium-rich stream will be generated that can be valorised in the form of fertilizer, promoting a new line of business for the sector and increasing the circularity of the water market.
As part of the project, a pilot plant will be designed and built to validate the NIMBI technology, which will be installed for 12 months at a WWTP operated by ACCIONA.
